Regions

South Rockies.

The weather is expected to be a mix of sun, cloud and flurries. If the sun comes out for extended periods of time, consider the hazard to be MODERATE at all elevations. For more information on dealing with these types of conditions, click here

Confidence

Moderate - Timing or intensity of solar radiation is uncertain

Weather Forecast

SATURDAY NIGHT - Mainly cloudy with isolated flurries / light southerly winds / alpine low temperature near -3 SUNDAY - A mix of sun and cloud with scattered flurries, up to 5 cm / light southwest wind / alpine high temperature near 0 / freezing level 2000 mMONDAY - A mix of sun and cloud with isolated flurries / light southerly winds / alpine high temperature near -1 / freezing level 2000 mTUESDAY - A mix of sun and cloud with isolated flurries / light easterly winds / alpine high temperature near -1 / freezing level 2000 m

Avalanche Summary

On Friday, there were reports of a few loose wet avalanches up to size 1.5 out of steep, sun-exposed terrain.

Snowpack Summary

The snow surface is likely a crust everywhere but high elevation, north facing terrain, where the snow remains dry. The crust will likely break down (melt) during the day as temperatures rise and if the sun comes out.The snowpack on sun exposed slopes in the alpine and all aspects at treeline and below may become moist or wet during the heat of the day, especially if the sun comes out. In these areas that have entered spring conditions, the avalanche hazard may fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day. Check out this guide to managing avalanche hazard during spring conditions HERE.In areas that remained more sheltered from the heat, like northerly aspects in the alpine, there is still a dry snowpack with a well settled slab sitting on weak facets (sugary snow).Lower down in the snowpack, the base is composed of weak facets.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
